【Professional Favorite】
Willie's renowned U3 series.

This is an excellent condition mouthpiece for bass trombone.

It is a best-selling model from willie's Custom Brass, a mouthpiece workshop in Yamanashi Prefecture.

It shows extremely minimal signs of use, and the gold plating retains its shine, maintaining a like-new condition.

■Features of this model (U3 SB 1M)
U3 Design: Balances control with a rich resonance.
This series is highly trusted by professionals and amateurs alike, from concert bands to orchestras.

1M Size:
Vast inner rim diameter equivalent to Bach 1G.
Ideal for those seeking overwhelming low-end support and a deep tone on the bass trombone.

SB (Straight Backbore):
Allows air to pass straight through, producing a clear and well-defined sound.

GP (Gold Plated) Finish:
Provides an extremely smooth feel on the lips, significantly enhancing sound projection and brilliance.

■Product Condition
Condition: Used only for testing, with minimal signs of use. It is in excellent condition with almost no noticeable scratches, dents, or shank wear.

Accessories:
Will be carefully packaged in its original box (as pictured) and shipped.

■Specifications
Type: For Large Shank
Finish: Gold Plated
This is a custom mouthpiece that would be very expensive to purchase at current retail prices.

If the size is right for you and you wish to upgrade your bass trombone sound, please consider this opportunity.

※Immediate purchase welcome
